To all whom it may concern:

Be it known that we, Gust-AVE HANSON and Cums A. NELSON, each a citizenof the United States and a resident of East 45 Berlin, in the county ofHartford and State of Connecticut, have invented new and ImprovedPortable Conveyors, of which the following is a specification.

Our invention relates to the class of con- 10 veyers above mentioned,and an object of our invention, among others, is to provide a conveyermember adjustably supported and including driving means carried by saidmember, and the latter being so arranged to that it may be positionedfor use under many and varyin conditions.

One form of evice embodying our invention and in the construction anduse 0 which the objects herein set out, as well'as so others, may beattained, is illustrated in the accompanying drawings, in which- Figure1 is a view of our improved conveyer looking from one side and shown ascut in vertical section. I a

Figure 2 is a top lan view of the same. Figure 3 (Sheet 1) is a View inside elevation on enlarged scale of a portion of our improved conve er.

Figure d (Sheet is a top view of one to end of the conveyer frame.

Figure 5 (Sheet H) is a detail view illustrating the arrangement of theguides for the conve er frame.

Figure 6 heet T) is a detail view of the motor and gear box.

Figure 7 (Sheet 1) is a side view of the same.

As its name indicates, our improved con veyer mayibe moved from place tolace, and to this end and as shown in the rawings, it embodies a base 10in the form" of a frame with sides and ends preferably formed of angleirons secured together in any suitable manner, the whole being supportedon wheels 11. In thepreterred conmruction these wheels are rotatablmounted in frames comprising forks 12 with shanks rotatably mounted inboxes 13- arranged in thecorners of the base, this being the well knowncaster construction.

The supporting frame for the conveyor member comprises four corner postsit upstanding from the base and secured thereto-in any suitable nnerwith side rails 15 each drum and wound thcrearound and passing oversheaves 22 rotatably mounted on the base and about sheaves 23 rotatablymounted at the upper ends of the corner f posts 14:. The outer ends ofeach of these cables is secured to a conveyor frame 24: at such pointsthat the latter will be supported against tipping movement.

This frame 24: comprises sides 25 preterably in the form of trusses andeach comprising a top and bottom rail connected by cross ieces, saidsides being preferably forme of angle iron to secure strength andrigidity. Rollers 26 are rotatably mounted on the top rails of saidframe to support an endless conveyor belt 27 passing around con veyerdrums 28 rotatably mounted at the ends of the conveyor frame.

The uprights 16 are properly spaced to provide guideways tor theconveyor frame,

the latter having guide studs 29 rejecting from the sides of thetoprails o the conveyer frame into the space between said posts.

A r box 304s suspended as vby none of brackets 31 from "the top rails ofthe conveyer frame and spannin the space therebetween near the lengtwise center thereof. A. motor bed 32 comprises an integral extensionfrom the gear box and projecting laterally therefrom support a motor 33in an inclined position with its shaft in line with an opening throughthe side of the box. The motor shaft may extend into this opening or aseparate shalt may be mounted in bearings therein, how

ever, whichever construction is empled,

there being a pinion 34 secur to said shaft and in mesh with a train 35of gears and pinions mounted in Marin the box, said train oomprismgagear 36 SQ"! in the side of ilCD cured to'a shaft 37 and carrying asprocket wheel 38 from which a chain 39 passes to a sprocket wheel 40secured to the shaft of one of the drums 28.

The bearings 41 for one of the conveyer drums 28 may be adjustablmounted as by means of brackets secure by bolts projecting through slots42 at one end of the sides of the top rails of the conveyer frame vadjusting screws 43 mounted in brackets in said top rails being employedtomove the drum, or permit its movement, to tighten or loosen theconveyer belt. The motor may be supplied with a plug at the end of anelectric cable 44 to convey current to said motor.

The gear box comprising a case including a support for a motor soarranged that it may be readily. connected to a system of gear mechanisminclosed within the box, and said mechanism including a driving memher,as the sprocket wheel 38, forms an important feature of our invention,as it enables a construction of the conveyer complete with its drivingmeans embodied therein all mounted upon a single supporting frame.

The device herein illustrated and described comprises a conveyer that isextremely simple in its construction, that is selfsupported andself-driven, and that will lend itself to uses under varying conditions,as either end may be placed at any elevation desired, within the rangepermitted by the frame, and without changing the elevation of theopposite end.

We claim 2-- 1. A conveyer comprising a base, a-supporting frame risingfrom the base, a conveyer frame rigid from end to end, extending onopposite sides, and supported for vertical movement on said supportingframe and projecting beyond the supporting frame on opposite sidesthereof, means for independently-liftin either end of said conveyerframe, sai lifting means being supported by said supporting frame, anda' conveyer movably mounted on said conveyer frame.

2. A conveyer comprising a base, a supporting frame rising from the baseand including two upright posts spaced apart to form guideways, aconveyor frame supported for vertical movement on said supporting frame,guides extending from the conveyer frame into said guldeways, meanssupported by. said supporting frame for independently liftin either endof the conveyer frame, an a conveyer movably mounted on the conveyerframe.

3. A conveyer comprising a base, a supporting frame rising from thebase, a conveyer frame comprising a structure rigid from end to endsuspended by means of cables supported by said supporting frame,

memo? drums for said cables, the latter being arranged to independentlylift either end of the conveyer frame, and means for rotating saiddrums.

4:. A conveyer comprising a base, a supportin frame including cornerposts rising from t e base, a conveyer frame rigid from end to endsuspended from said supporting frame and between the corner posts bymeans of cables, said conveyer frame pro- Ljecting beyond the supportingframe on opposite sides thereof, means for operating said cables toindependently lift either old of the conveyer frame, and a conveyermovably mounted on the conveyer frame.
